Abstract
This paper investigates the efficiency of the combination of the Ping-pong Optimized Pulse Shaping-Orthogonal Frequency Division Multiplexing (POPS-OFDM) algorithm with the Time Reversal (TR) technique. This algorithm optimizes the transmit and receive OFDM waveforms with a significant reduction in the system Inter-Carrier Interference (ICI)/Inter-Symbol Interference (ISI) and guarantees maximal Signal to Interference plus Noise Ratio (SINR) for realistic mobile radio channels in 5G Systems. To this end, we characterize the scattering function of the TR channel and we derive the closed-form expression of the SINR as a Generalized Rayleigh Quotient. Numerical analysis reveals a significant gain in SINR and Out-Of-Band (OOB) emissions, brought by the proposed TR-POPS-OFDM approach.
本文研究了乒乓优化脉冲整形-正交频分复用(POPS-OFDM)算法与时间反转(TR)技术相结合的效率。该算法优化了发送和接收OFDM波形,显著降低了系统载波间干扰(ICI)/符号间干扰(ISI),并保证了5G系统中实际移动无线电信道的最大信噪比(SINR)。为此,我们对TR信道的散射函数进行了表征,并导出了SINR的广义瑞利商的封闭表达式。数值分析表明,提出的tr - pop - ofdm方法带来了信噪比和带外(OOB)发射的显著增益。
